Extra Info
• Rebooting. When a TV is constantly rebooting due to
internal problems, most of the time no errors will be logged
or blinked. This rebooting can be recognized via a ComPair
interface and Hyperterminal (for Hyperterminal settings,
see section “5.8
Fault Finding and Repair Tips, 5.8.6
Logging). It’s shown that the loggings which are generated
by the main software keep continuing.
• Error 13 (I
2
C bus M3, SSB + SRF bus blocked). Current
situation: when this error occurs, the TV can reboot due to
the blocked bus. The best way for further diagnosis here, is
to check the logging output.
• Error 14 (I
2
C bus M2, BE bus blocked). Current situation:
when this error occurs. The best way for further diagnosis
here, is to check the logging output.
• Error 18 (I
2
C bus M1, FE bus blocked). Current situation:
when this error occurs. The best way for further diagnosis
here, is to check the logging output.
• Error 15 (Fusion doesn’t boot). Indicates that the main
processor was not able to read his bootscript. This error will
point to a hardware problem around the Fusion (supplies
not OK, Fusion device completely dead, link between Mips
and Standby Processor broken, etc...)
Other root causes for this error can be due to hardware
problems regarding the DDR’s and the bootscript reading
from the Fusion device.
• Error 16 (12V). This voltage is made in the power supply
and results in protection (LAYER 1 error = 3) in case of
absence. When SDM (maintain grounding continuously) is
activated we see blinking LED LAYER 2 error = 16.
• Error 17 (Display Supply). “Power OK” not applicable.
• Error 23 (HDMI mux). When there is no I
2
C
communication towards the HDMI mux after start-up,
LAYER 2 error = 23 will be logged and displayed via the
blinking LED procedure if SDM is switched on.
• Error 24 (I2C switch). When there is no I
2
C
communication towards the I
2
C switch, LAYER 2
error = 24 will be logged and displayed via the blinking LED
procedure when SDM is switched on.
• Error 27 (Channel dec DVB-T2). When there is no I
2
C
communication towards the DVB-T channel decoder,
LAYER 2 error = 27 will be logged and displayed via the
blinking LED procedure if SDM is switched on.
• Error 28 (Channel dec DVB-S2). When there is no I
2
C
communication towards the DVB-S channel decoder,
LAYER 2 error = 28 will be logged and displayed via the
blinking LED procedure if SDM is switched on.
• Error 31 (Lnb controller). When there is no I
2
C
communication towards this device, LAYER 2 error = 31
will be logged and displayed via the blinking LED
procedure if SDM is activated.
• Error 34 (Tuner). When there is no I
2
C communication
towards the tuner during start-up, LAYER 2 error = 34 will
be logged and displayed via the blinking LED procedure
when SDM is switched on.
• Error 35 (main NVM). When there is no I
2
C
communication towards the main NVM during start-up,
LAYER 2 error = 35 will be displayed via the blinking LED
procedure when SDM is switched “on”. All service modes
(CSM, SAM and SDM) are accessible during this failure,
observed in the Uart logging as follows: "<< ERROR >>>
PFPOW_.C: First Error (id19, Layer_1= 2 Layer_= 35)".
• Error 36 (Tuner DVB-S). When there is no I
2
C
communication towards the DVB-S tuner during start-up,
LAYER 2 error = 36 will be logged and displayed via the
blinking LED procedure when SDM is switched “on”.
• Error 37 (Class-D). When there is no I
2
C communication
towards the Class-D amplifier during start-up, LAYER 2
error = 37 will be logged and displayed via the blinking LED
procedure when SDM is switched “on”.
• Error 38 (microProcessor PQ). When there is no I
2
C
communication towards this processor device during start-
up, LAYER 2 error = 38 will be logged and displayed via
the blinking LED procedure when SDM is switched “on”.
This device supports the backlight + boost pwm control,
scanning, 3D drive.
• Error 41 (I/O Expander). When there is no I
2
C
communication towards this processor device during start-
up, LAYER 2 error = 41 will be logged and displayed via
the blinking LED procedure when SDM is switched “on”.
• Error 42 (Temp sensor). Only applicable for TV sets
equipped/stuffed with temperature devices.
• Error 43 (Light sensor). When there is no I
2
C
communication towards the light sensor device during
start-up, LAYER 2 error = 43 will be logged and displayed
via the blinking LED procedure when SDM is switched “on”.
• Error 44 (Touch control). When there is no I
2
C
communication towards the touch control micro processor
during start-up, LAYER 2 error = 44 will be logged and
